Hi,
I have a problem starting up an I/O node. It is one of 3 servers that we run v2.8.1 on over Inifiniband. It is not used for metadata. After a finding a file which had '?--?--?' like permissions, I decided to restart the pvfs servers and remount all of the clients. Now, one of the three I/O nodes can't start it's pvfs2-server. The other two start correctly. Here is the server log from the problem server: [D 02/08 19:40] PVFS2 Server version 2.8.1 starting. [E 02/08 19:40] dbpf_dspace_iterate_handles_op_svc: Invalid argument [E 02/08 19:40] Error adding handle range 1537228672809129303-3074457345618258602,6148914691236517203-7686143364045646502 to filesystem pvfs2-fs [E 02/08 19:40] Error: Could not initialize server interfaces; aborting. [E 02/08 19:40] Error: Could not initialize server; aborting. I am also using db4-4.2.52-7.1 of the DB software. Reading through the previous mailing lists discussions, I found that running db_recover on the .db files (after backing them up) could be helpful. The only .db file which has any problems with verify is dataspace_attributes.db on the problem I/O node. Here is what it reports: >># db_verify -o dataspace_attributes.db db_verify: Page 865: item 57 of unrecognizable type db_verify: Page 865: gap between items at offset 1376 db_verify: Page 865: item order check unsafe: skipping db_verify: DB->verify: dataspace_attributes.db: DB_VERIFY_BAD: Database verification failed So I tried db_recover -v in the same directory and in the directory above (I am not sure where to run it) and all I get is: db_recover: Finding last valid log LSN: file: 1 offset 28 and a small binary file named "log.0000000001". This step seems to do nothing, i.e. the db_verify report doesn't change after this. I have also tried db_dump -r followed by db_load and this also does not change the db_verify output. Is there anything else I can do except wipe the filesystem and rebuild? Thanks for any help I can get. Eric J.
